weeks ago. what police are now saying. good evening. and it's great to have you with us to start another week here. and we do begin with president trump's own words today about the dead lly school shooting. the president hosting the nation's governors at the white house, criticizing the response and telling the governors he would have run into the school even without a weapon. abc's chief white house correspondent jonathan karl leading us off. >> reporter: president trump said today he likely would have showed courage under fire and run in to stoneman douglas high school himself to confront the killer. >> you know, i really believe, you don't know until you test it, but i think i would have run in there without a weapon. i think you in this room would have done that, too. >> reporter: speaking to a large bipartisan group of governors, the president revealed he had lunch sunday with wayne lapierre, leader of the nra, which is now under intense pressure.

at least 16 corporations, including delta airlines, metlife, and several major rental car companies have severed their ties with the nra since the parkland shooting. the president called nra leaders patriots, but he insisted he is not afraid to oppose them. >> and i want to tell you, they want to do something. i said, fellas, we have to do something. it's too long now. we have to do something. don't worry about the nra, they're on our side. half of you are so afraid of the nra. there's nothing to be afraid of, and you know what, if they're not with you, we have to fight them every once in a while. that's okay. >> reporter: and one idea the president has embraced would require a fight. a plan to raise the minimum age for buying a rifle from 18 to 21. the nra opposes the idea, and since the lunch with the president, he hasn't mentioned it, either. >> in concept, the president still supports it, but in terms of legislation, we'd need to see what that looks like before we weigh in further. >> reporter: the idea the president seems most enthusiastic about remains allowing qualified teachers and school officials to carry

concealed weapons to school. >> i want highly trained people that have a natural talent, like hitting a baseball, or hitting a golf ball, or putting. >> reporter: but the governor of washington state, democrat jay inslee, rose to confront the president. >> i've listened to the first grade teachers that don't want to be pistol packing. we need to listen that, educators should educate, and they should not be foisted upon this responsibility of packing heat in first grade classes, so i just suggest we need a little less tweeting here, a little more listening. >> reporter: the president immediately turned to republican greg abbot, governor of texas, one of a handful of states that allows qualified teachers to carry concealed weapons. abbott said some schools actually have warning signs out front. >> warning anybody coming in there that if they attempt to cause any harm, they're going to be in trouble. >> well, i think that's great. >> jon karl with us live tonight at the white house. and jon, as the president was addressing the governors, we

know first lady me lynn ya trump was speaking to their spouses. she praised the high school students that have spoken out about gun control. listen to them. >> i have been heartened to hear children across this country using their choices to speak out and try to create change. they're our future and they deserve a voice. >> jon, the students have been taking on the nra. president trump revealing that he had lunch with the head of the nra over the weekend? >> reporter: and you heard him say that he's willing to take on the nra, to fight the nra, but david, he has not supported a single piece of legislation, a single bill, that the nra opposes, and this much is clear. unless the president leads, congress is not going to act on any gun measures. he is going to have to push the republican leadership to do it or they will not act. >> all right, jon karl leading us off on a monday night. jon, thank you. meantime, for the first time, the deputy branded a coward by some is now responding

tonight. he's accused of being outside the school building but failing to go inside to confront the shooter as it was all under way. abc's vick to oquendo with the new statement tonight. >> reporter: tonight, as teachers and students begin returning to the scene of that horrific school shooting, that school resource officer, accused of waiting outside of the building while the rampage unfolded, defending himself, saying in a letter through his lawyer, "the allegations that mr. peterson was a coward and failed to meet the standards of police officers are patently untrue." former deputy scot peterson claims he initially received a call of firecrackers, and that once he arrived at the building, he heard gunshots, but believed that those gunshots were originating from outside of any of the buildings. peterson, calling the sheriff's strong statements about him -- >> devastated. sick to my stomach. >> reporter: quote, uncalled for attacks upon his character. this, as sheriff scott israel is on the defensive himself. >> i have given amazing leadership to this agency. >> amazing leadership? >> reporter: israel now investigating reports from nearby coral springs police

officers who also responded to the school that several other broward county deputies waited instead of rushing into the school during the shooting, but israel says the tapes he has reviewed don't back up this claim. and now, calls from 74 florida republicans for the sheriff, a democrat who has spoken out against arming teachers, to be suspended for his department's kwl ignoring repeated warning signs" about suspected shooter nikolas cruz. the sheriff's office responded to 18 calls related to cruz, two of those calls now under review, including one call in november saying cruz could be a school shooter in the making. >> the caller, as you know, came from massachusetts. she told the deputy that the subject, the eventual killer, was somewhere in palm beach county. >> reporter: the sheriff then asked, did the person who received that call follow up? >> indication at this point is that he did not. >> victor oquendo live with us tonight from outside the school. and rick scott, a republican, who has already backed raising

the minimum wage to buy firearms to 21 now, says he disagrees with the president's plan to arm some teachers? >> reporter: david, the governor rarely disagrees with the president, but here he is, on the record, saying he'd rather see teachers teach and focus on making sure law enforcement, with the proper training, is in place to protect the students. david? >> vick to oquendo tonight. victor, thank you. next this evening, the deadly storm system. at least eight people killed. a dozen confirmed tornadoes hitting four states, including kentucky. many communities under water tonight, as we now track a new system moving into the east, and abc's marcus moore in the storm zone. >> reporter: tonight, millions reeling from a weekend tornado outbreak and severe flooding. residents frantically digging through debris of this clarksville, tennessee, home. >> they just rescued that dog from the rubble. >> reporter: a family pet surviving an ef-2 twister, winds up to 125 miles per hour. >> cladjour way and his wife

this could potentially become a nor'easter on friday. the main concern is certain little for the rain coming over the flood zone. >> all right, tracking it through the end of the week. rob, thank you. to the supreme court tonight. today, rejecting the trump administration's request to make immediate action on daca. the court declining the petition to review a federal judge's ruling, keeping the program in place for now. the decision means the government must continue renewing permits for now, allowing 700,000 dreamers to stay in the country. the deadline for the program had been march 5th. there is also news tonight on the russia investigation, and after the memo written by republicans in the house, now the democratic response released. the president responding by calling into a cable show saturday night and tonight here, the new fallout. here's abc's chief justice correspondent pierre thomas tonight. >> reporter: tonight, house democrat s challenging republicans claims that the russia collusion. >> this is not the deep state

opposing donald trump. that's nonsense. >> reporter: but president trump says the democrat's memo only reinforces with republicans had already found. >> certainly the memo was a nothing. a lot of bad things happened on the other side. not on this side, but on the other side. >> reporter: the republican memo drafted by the staff of house intelligence committee chairman devin nunes, a close trump ally, concluded the justice department acted improperly in on staining a secret surveillance warrant against carter page. nunes claimed the fbi relied largely on information on a dossier. he insisted the court was never told steele's work was politically motivated and paid in part by the clinton campaign. >> to have a secret court that gets abused like this is totally unacceptable. >> reporter: in the memo, the democrat says the fbi obtained the warrant against page after information obtained through multiple independent sources corroborated steele's reporting

about him. those sources seemingly redacted here. democrats also find the justice department officials repeatedly informed the court about steele's background, credibility and potential bias against trump. >> all right, so, pierre thomas with us live tonight from capitol hill. and pierre, republicans argue the steele dossier is at the heart of the russia investigation, bull in this memo, democrats try to make it clear that the fbi started investigating well before the fbi even saw the dossier. >> reporter: that's right, david. the democrats say the fbi launched their investigation a full seven weeks before they were even made aware of the steele dossier. david? >> pierre thomas tonight. thank you. overseas tonight, reports of a deadly chemical attack in syria. victims treated for alleged exposure to chlorine gas. the area under intense attack by the assad regime for more than a week now. russian president, vladimir putin, has ordered a daily five-hour, quote, humanitarian pause in that fighting. and we have new reporting

explosives expert practicing his craft. >> anybody can shoot a gun, demo is something els it's a lot more fun. >> reporter: the special forces united states had never come under fire, but it is gear from this nat geo video, this was hostile territory. >> in this area is isis, and then in this area, we have boko haram. >> reporter: on october 3rd. >> wright, johnson and nine other others headed out meet local leaders, but on their way back, without air cover, heavy weapons, or heavy armor were sent to a far more dangerous mission.to try to dangerous mission. to try to capture or kill a local terrorist. 24 hours later, they were ambushed. >> there's never a doubt in my mind how he fought, and what he would do for any member of that team. and i am proud. >> those soldiers just days before that mission. martha raddatz with us tonight. and martha, we do know that the pentagon is expected to release its findings in the coming days? >> reporter: that's exactly right, david. it's been an exhaustive investigation as to why that mission dramatically changed. but the families of the fallen
